Abstract :
A compact equivalent circuit using a complex transconductance is proposed for linearity design in the multiple gated transistors configuration. This complex transconductance gives better design parameters as compared to previous published analysis. Measured data show that the designed mixer has conversion gain of 4.7 dB, input return loss of 9 dB, and third-order input intercept point (IIP3) of 10.3 dBm with only 1.8 mW power dissipation under 1-V supply voltage
